SPECIFICATION forming part of Letters Patent No. 577,155, dated February16, 1897. Ap lication med m 30,1896. Serial No. 601,009. (No model.)

To all whom it may concern:

Be it known that 1, JOHN W. BRAGGER, a citizen of the United States,residing at Vatertown, in the county of Jefferson and State fulImprovement in Bicycle-Lamps, of which This invention relates to thatclass of lamps which are principally used on bicycles, and has for itsobjects to improve the construction of the air inlets and exits in suchmanner as to protect the flame more effectively against extinguishmentby the reversal of the air-currents in the lamp; also to improve theconstruction of the burner-gallery and its connections with thelamp-body and oil-fount in such manner as to produce a simple, durable,and convenient construction of these parts; also to connect theside-light frames with the lamp-body by spring devices whereby theseframes are held either openor shut; also to provide a simple andefficient screw-fastening for the front lens or glass, and finally toprovide the wick-tube with means for returning to the same the oil whichhas escaped from the top of the wick-tube.

In the accompanying drawings, consisting a lamp provided with myimprovements. Fig. 2 is a horizontal section through one of the Fig. 3is a detached perspective view of one of the side Fig. 4 is a horizontalsection, similar to Fig. 2, showing the side light partly opened. Fig. 5is a vertical longitudinal sect-ion of the lamp. Fig. 6 is a horizontalsection in line 6 6, Fig. 5. Fig. 7 is a vertical section of theburner-gallery and connecting parts in line 7 7, Fig. 6. Fig. 8 is avertical section of the burner-gallery detached.

Like letters of reference refer to like parts in the several figures.

A represents the oil-pot, and CL the wicktube, secured with its lowerend in the top plate of the oil-pot, which top plate is preferablyconstructed with a depressed central portion a, in which the housing Bof the wickraiser b is secured.

0 represents the burner-gallery, which is composed of a horizontal plateor diaphragm c and a depending marginal cylindrical portion 0, bothsuitably perforated and formed in one piece of sheet metal. The galleryrests with the lower edge of its marginal portion 0 upon the top of theoil-pot.

cl represents an annular bead or hollow rim formed on the horizontalplate 0 of the gallery near the marginal edge thereof and formin g anupwardly-projecting shoulder, against the outer side of which the loweredge of the lamp-body rests.

E represents an annular plate which is arranged at a short distanceabove the burnergallery and which is provided at its inner edge with anupwardly-projecting collar e. The burnercone F rests upon this plateagainst the outer side of the collar (2, as clearly shown in Fig. 5. Theplate E rests upon hollow stay bosses d, which are preferably stampedupon the plate a of the burner-gallery, and is secured to the latter andto the oil-pot by vertical bolts f, which pass, preferably, throughthese stay-bosses and secure the gallery and supporting-plate to theoil-pot.

G represents the outer cylindrical shell of the lamp-body, which restswith its lower por-,

tion upon the plate 0 of the burner-gallery and against the outer sideof the annular rim d thereof. This shell carries at its upper end anupwardly-converging curved breast-piece g, which carries in turn aperforated cylindrical top collar 9, having at its upper end animperforate annular plate 9 The latter supports thedome or cap 9 whichoverhangs with its lower perforated flange the imperforate top plate g Hrepresents the inner cylindrical shell of the lamp-body, which isarranged in a wellknown manner at such a distance inwardly from theouter shell as to form an annular air-passage H of suitable widthbetween both shells. The inner shell rests with its lower edge upon theannular plate E, near the outer edge of the latter.

inner shell carries a cylindrical collar h of slightly-smaller diameterthan the inner shell and forming a continuation of the latter, and thiscollar carries the upwardly tapering chimney h, which opens underneaththe cap or dome g '5 represents an annular row of perforations The upperedge of-thev formed in the outer shell immediately above the burner-gallery, and 2" represents a similar row of perforations formed inthe upper portion of the same shell opposite the upper portion of theinner shell.

j represents one or more annular rows of perforations formed in thelower portion of the inner shell opposite the lower row of perforationsin the outer shell, and j represents an annular row of perforationsformed in the lower portion of the cylindrical collar h of the innershell. I

In the ordinary operation of the lamp the air for the supply of theflame enters through the perforated burner-gallery and passes underneaththe burner-cone and into the inner shell outside of the burner-cone.Under certain conditions of motion air for the support of the flame isalso derived from the openings in the upper perforated collar g, whichair passes downwardly through the annular space between the two shells;The openings at the upper and lower ends of the inner and outer shellspermit the air to partially escape or cushion in raising and loweringthe lamp suddenly, and this prevents the air from extinguishing theflame under sudden vertical movements.

K represents a flat stud, and L a springcatch, which project outwardlyfrom diametrically opposite sides of the burner-gallery above thehorizontal plate thereof and engage in openings formed in diametricallyopposite sides of the lower portion of the outer shell. The spring-catchis provided with a thumb-piece Z, which is arranged below the horizontalplate of the gallery and projects through the marginal portion 0thereof. This arrangement of the attaching devices is very simple andpermits the oil-pot'to be connected with the lamp-body in either of twopositions, so that the wick-raiser shaft can be made to project on oneside or the other of the lamp, as may be most convenient.

M represents two square side tubes which are arranged on opposite sidesof the lamp body and extend from the inner to the outer shell andconnect the side portions of these shells, while permitting light topass laterally from the opening in the inner to the opening in the outershell for the illumination of the side lights in a well-known manner.

N represents the frame or door of each side light fitted against theouter side of the side opening in the outer shell and containing usuallya colored glass or other signal. Each frame or door is pivoted by asleeve n to the upright bar 1) of a bent bifurcated wire spring P,having two arms 19, which are arranged on the inner side of the outershell. The ends of these spring-arms are secured to the shell by anysuitable means, preferably by a clamping-plate 19 which is riveted tothe shelland grasps the ends of the spring-arms.

The frame ofv the side light is provided with a projection extending ashort distance beyond its pivotal connection with the spring two shortarms a being shown. In turning the frame on its pivot in opening theside light these projecting arms at brace themselves against the outerside of the lamp-body and form rocking pivots on which the frame turns,as indicated in Fig. 4. As the frame turns on the ends of these armsduring the opening movement, the pivotal connection of the frame withthe spring moves outwardly or away from the lamp-bod y, whereby thespring is forced outwardly and strained. This 0011- tinues until thearms have passed the deadcenter, when the pivotal connection is free toapproach the side of the lamp-body under the action of the spring, whichnow quickly completes the opening movement and then holds the frameopen. During the closing movement of the frame the spring is firststrained and then quickly completes the closing movement in the samemanner. This device for holding the side light open or shut isparticularly desirable because it does not require a long-continuedhandling of the sidelight frame, which is often hot and not easilyhandled.

Q, represents the forwardlyflaring tube which extends from the innershell through the outer shell and forwardly beyond the latter and whichreceives the front lens or glass R. The latter rests against an annularshoulder q, formed in the front portion of this tube at the base ofaninternal screw-thread g.

Q, is a screw-collar which engages in said screw thread and which clampsthe lens against the supporting-shoulder by means of a yielding flange(1 formed at the inner end of the screw-collar. The latter is formed ofsheet metal, and the flange is formed in one piece with the collar andextends inwardly from the inner end of the collar. As the flange is madeof sheet metal, it is yielding and so bears snuglya'gainst the lens andholds the latter securely against rattling.

S represents a cup secured to the wick-tube above the plate of theburner-gallery, and 3 is an opening formed in the wick-tube immediatelyabove the bottom of this cup, so that any oil which may have escapedfrom the top of the wick-tube is caught in this cup and returns throughthis opening into the wicktube.

T represents the usual reflector arranged in the inner shell of the lampbody.

I claim as my invention- 1. The combination with the oil-pot, of aburnengallery resting thereon and consisting of a perforated diaphragmprovided with a marginal flange having air-inlets, an outer shellresting on said diaphragm and provided with perforations near its lowerend and with air-inlets near its upper end, an inner shell having itslower end supported above said diaphragm and provided with perforationsnear its lower end and in its upper portion,

and a burner arranged within said inner shell and having its air-spaceincommunication with the space between the inner and outer shells,substantially as set forth.

2. The combination with the oil-pot, of a burner-gallery composed of ahorizontal perforated plate and a perforated depending marginal flangeformed integrally therewith and having a raised annular rim and raisedbosses formed integrally with said horizontal plate, an annularsupporting-plate resting on said bosses, bolts connecting saidsupportingplate and perforated plate with the oil-pot, and an outershell resting on said horizontal plate outside of said rim,substantially as set forth.

3. The combination with the lamp-body, of a spring .composed of apivot-bar and bent arms connected with the ends of said bar and securedat their ends to the lamp-b dy, and a signal frame or door pivoted tosaid bar between the arms of said spring and provided with a projectionextending beyond said pivotbar and adapted to bear against the lampbody,substantially as set forth.
